Hi, thanks for writing to HCM.
Based on the description of symptoms, you could have suffered a fracture
or a soft tissue injury
resulting in hematoma
An xray of the injured area will diagnose a fracture and it has to be treated accordingly either with a cast or surgery.
If it's only a soft tissue injury, conservative management is followed in the form of -
* Rest to the injured part and adequate support or protection
* Ice packing once in 3 hours to reduce the pain
* elastic compression bandage over the swollen area
* Limb elevation
medications as needed
Hope this information is helpful. Good day
